Mares Dual Octopus

This lightweight Mares Dual Octopus is made of techno-polymer features an oversized silicone purge button so that the purge button is easy to push. All Mares second stages are a reliable downstream valve design and offer the unique patented Vortex Assisted Design (VAD) system. The air bypass tube conveys air to the mouthpiece creating a swirling vortex with a low-pressure area in the center that keeps the diaphragm down during inhalation, for very sensitive and easy breathing at all depths. This pneumatically assisted designed (P.A.D.) safe second is equipped with an adjustable breathing knob for the ultimate in breathing comfort.

Furthermore, the compact and ergonomic exhaust tee ensures superior hydrodynamic performance and reduced exhalation resistance. The mouthpiece is made of soft hypoallergenic silicone: limiting jaw fatigue and offering a secure fit even after very long dives. Mares developed the Superflex hose after many years of testing and research. The results achieved far surpassed the tests required by EN250. Hose is extremely light weight and exceptionally soft, guaranteeing the maximum freedom of movement and further reducing jaw fatigue. The regulator comes with a high visibility yellow Superflex hose that is a 3/8" threaded high flow hose and is 39.4" (100 cm) in length. The regulators total weight is 12.6 oz. (357 g) with hose.
